DEVICE FOR CONTROLLING THE OPERATION OF WORKMENS TIME CLOCKS.

Application filed October 27, 1923. Serial No. 671,233.

This invention relates to time recording mechanisms, generally called time clocks, which are used at a works or ofiice entrance to register the arrival and departure of the employees. 1 v

More particularly the invention relates to controlling means for time clocks of the type wherein time is recorded by printing on a card inserted in a card receiving slot in the clock case.

One important object of the invention is to provide an improved means operated by the passage of the employee which prevents errors in the stamping of the employees card.

A secondobject is to provide improved means of time clock control which operates to prevent a card being'stamped more than once during the passage of an employee past the clock.

A third important object of the invention is to provide improved time clock controlling mechanism which acts to prevent an employee from stamping more than one card during his movement past the clock.

A fourth object of the invention is to provide an improved time clock control which restrains the employee from leaving the vicinity of the clock without operating the stamping mechanism by the insertion of a card in'the proper place.

A fifth object of the invention is to provide improved means for preventing surreptitious tampering with the time mechanism of a time clock while holding the operating lever in depressed position.

A sixth object of the invention is to provide an improved form of automatic reversing mechanism for use in connection with such a clock, the mechanism being arranged to control the direction of movement of the employees.

With the above and other objects in view as will be hereinafter apparent, the inven tion consists in general of certain details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

The invention consists, in general of a detail semidiagrammatic pair of turnstiles A and'B arranged adja- I v cent the entrance of the works at opposite ends of a passage or runway P having at one side a time clock. C and at the other a guard rail D. Thus the workmen on entering and leaving the works; pass through the turnstiles. successively inorder to operate the time clock and stamp the time on the cards used for this purpose. A

, Considering first the turnstiles. Eacho'f these turnstiles consists of a standard or base 2 and 3, respectively wherein is journalled a vertical shaft -l carrying at its upper end a hub 6 from which radiate arms 5. On each shaft l is an edge ratchet 7 while beneath the hub is a face ratchet 8 having ratchet teeth on its under surface engaged by the bevelled end of a vertically guided pawl rod 11 which is held in yieldably raised position by a spring 12 surrounding the pawl rod and bearing at its lower end against the bottom of the standard 2 and at its upper end against a collar 18 fixed on the rod 11. The lower end of the rod 11 is connected by a pin 15 with the normally raised end of a pedal lat which is supported at its other end by trunnions 16 mounted in bearings 17. On each of the turnstile arms 5 is an upstanding pin 9. The upper end of each turnstile is covered by a hood or housing 18 and depending from this hood is a stud 2O whereon is mount-ed a don.- ble ended pawl 19, the pawl being pivoted centrally of its length and so positioned that, upon being rocked in one direction one end engages the ratchet 7 while opposite rocking of the pawl engages its other end with said ratchet. Thus the pawl prevents turning oi the turnstile in one direction or the other in accordance with the engagement of one or the other of its ends. This pawl is formed somewhat like the anchor of a watch escapement and in order to permit the engaged end to ride out of the spaces between the ratchet teeth upon the turnstile being turned in the proper direction there is provided a pair of spaced leaf springs 22 which extend late 'ally from the back of the pawl and embrace a pin 21 mounted on a sliding rod 23. This rod passes from one turnstile to the other through the time clock O and since the turnstile construction is alike at each end a longitudinal sliding movement of the rod serves to change the positions of the pawls 19 in each turnstile simultaneously. Thus by moving the rod to the right as in Figure 2 trailic is permitted through the runway P in the direction of the arrow P while movement to the left allows trattic to pass in the opposite direction. From one cause or another it may happen that the rod is either not fully moved to the right or left or becomes somewhat displaced from its correct position. To ensure the rod being fully moved there is provided at each turnstile a rocking lever 24: which is pivoted intermediate its ends to a stud 25 depending from the housing 18. This lever has a slot at one end engaging a pin 26 on the rod 23 and its other end moves between the positions shown at the right and left of Figure 2, passing through the path of the pins 9 during this movement. Under these conditions if the rod 23 is in any position intermediate its extreme right and left positions the lever 24 will be engaged by one of the pins 9 upon either turnstile being rotated so that the rocking lever will be moved and thus move the rod 23 to its extreme position. This rod 23 is preferably termed the reversing rod.

It is here to be observed that the ratchets 8 are oppositely arranged so that, irrespective of the positions of the pawls 19 a person can only rotate the turnstiles for exit from the passage P from inside such passage by stepping on the treadle 1t at the respective end and in order to prevent this being done from the outside guards 10 are provided which depend from the arms 5 to points ad jacent the floor just enough clearance being allowed to permit the guards to pass over the pedals 14.

Depending from each hood 18 is a pivot pin 28 on which is mounted a bell crank 27 pivotally connected at 30 to a rod 20 which extends through the clock O. This rod is preferably termed the lock rod. On the bell crank is pivoted a bell crank lever 31, one arm of which is held against a pin 32 by a spring Now this rod 29 is movable to the right and to the left and, as can be seen in Figure 2, when the rod is moved to the right, the right hand lever 31 lies in the path of the pins 9 on the right hand turnstile, the left hand lever 31 being out of the path of the left hand pins 9. There also pivoted on each of the pins 28 a lever A having one arm in the path of the pins 9 and the other arm provided with a lug 35 held against the side of the bell crank lever 27 adjacent the pivot 30 by a spring 36, which has one end connected to the lever 3i and its other end connected to the casing 18.

Now consider Figure 2, we will suppose that an employee enters through the turnstile A. owing to the relation of the lever 34 with the bell crank 27. the lever swings free without moving the hell crank when the pin 9 engages said lever, consequently there will be no movement of the rod 29. \Vhen the employee passes out one of the pins 9 on the turns e l3 strikes the small bell crank and si .g the bell crank 27 so that the rod 29 is shifted to the left.

\ nhin the time clock 0. as shown in Figshown} by means of the shaft and gears 4-1 and -12. These type wheels are connected in the usual manner but the specific construction which compels said wheels to move in proper relation common to time clocks andv is not here shown. Adjacent the type wheels the casing of the clock O is provided with a card chute or guide 43 turnishing the usual mean for permitting the insertion of the cards tor stamping. In front of the type wheels is the printing arm or platen it which is pivoted on a pin 45 carried by an arm 46 which is in turn pivoted on a cross shaft 53. On the arm 46 is a stop pin 47 spring 48 connecting the hammer and upper end of the lever 46. At 49 is the operating lever and this lever is pivoted likewise on the cross shaft 53. On the lever 49 is pivoted a hook 50 which is held in engage ment with a post 51 on the lever 46 by means of spring 52. At 54 is a stop which limits the movement of the lever 46 rearwardly, said lever being held against said stop by means of a spring 55 connecting the lever and post 56. The book 50 is provided with a cam surface 58 and in the path of movement of this cam surface is a throw-out pin 57. Now under these conditions depression of the lever 49 will rock the entire lever system in such manner that the hammer 44 will move away from the type wheels. On the hook surface 58 engaging the pin 57 the post 51 will be freed from the hook 50 and the spring'55 will throw the hammer quickly back to the type rolls or wheels and thus print the card inserted in receiver 43.

Pivoted at its upper end to the lever 49 is link 59 which has its lower end connected to one arm of a lever 60 pivoted on the cross shaft 61. This lever 60 carries a pawl 62 mounted on pivot 63 and held in normal alignment with the lever 60 by spring 64 having one of its ends secured at 65. In the path of the pawl there is supported a ratchet 66. This pawl and ratchet are so arranged that the point of the pawl 62 engages the ratchet teeth on both the upper and downward motion of the trip lever 60 in such manner that the lever must complete its full movement before its return in the opposite direction can be effected. This trip lever 60 is normally held in the position, shown in Figure 7 by means of the spring 132. Attached to the reverse rod 23 is a bracket 74 from which are suspended the guide rods 70. On these rods slides the crosshead 69 which is normally forced downward by means of the spring 75. On the crosshead 69 is a pin 71 which engages one arm of an inverted T- shaped lever 72 having in its stem a slot 76 engaging a pin 73 on the rod 29. At 77 is a rock arm which is fixed upon a shaft 78 pivoted in the lower part of the casing and the rock arm is adapted to be restrained from forward movement by means of a latch 79 normally held in engagement with pin 80 forming a limit stop by means of a spring 81 secured to a post 82. The end of the latch 79 engages behind a shoulder 129 on the arm 77 but is raised above this shoulder by the action of the lever 60 in striking a projection 127 on the latch, upon depression of the lever 49. On the arm 77 is a' spring 83 which forms a latch for the lever 60 when the arm 77 moves forward and the lever 60 returns to its normal position, shown in Figure7. Thus after one operation of the le-' ver 49 a second operation is prevented. Furthermore in order to render it impossible to insert a second card the lock shaft 78 is provided with a rock arm 86 extending forwardly from the shaft and connected by a rod 87 with a bell crank lever 88 pivoted adjacent the chute 43 on a pivot 89 arranged to swing beneath the chute 43 and close off admission of the cards to the case of the clock. Thus when the operating lever is depressed not only will it be prevented from a second depression but a second card can not even be inserted. A spring 130 holds the arm 86 downward and at the upper end of the rod 87 there is provided a spring 131 providing a yielding connection between the rod 87 and bell crank 88, so that as a card is put in the chute the chute will be closed until the card is withdrawn.

The several steps just described. can be clearly seen by referring to Figures 10, 11 and 12. The lower end of the clock operated shaft 40 is indicated at 90 (see Fig. 8) and at the bottom of this shaft is a worm 91 which meshes with a worm wheel 92 fixed on a shaft 104. is such that the worm wheel will rotate once in twenty-foul. hours. rirranged about the periphery of this worm wheel is a series of lugs 93 which engage surcessivcly with a cam projection 95 on a lever 94 pivoted at one end and having its other end urged downward by means of a spring secured to a post 101. Pivotcd to the free end of lever 94 is a pawl 96 which engages the teeth 97 of a ratchet 98 mounted on the shaf 104. From Figure 8 it will be seen this construc-, tion is such that as wheel 92 rotates the le ver 94 oscillates and causes step by step rotation of the ratchet 98. This rati'liet 98 is fixed on a sleeve 102 which also carries the ratchet or cam wheel .103 provided with outer cam portions 105 and inner cam portions 106. This cam wheel engages one or the other of the pins 107 on the rod 23.

The Wheel 37 is the minute type wheel and rotating with this wheel a ratchet wheel 108. termed the finder wheel and having 60 notches therein corresponding to the indications of 60 minutes. slidably mounted beneath this wheel in brawl; and 110 is tinder rod 111 bevelled at its upper end to enter either one of the notches of wheel 108. This finder rod is normally held in a depressed position by means of a spring); 112 bearing at its upper end against the guide 109 and its lower end against a collar 113 onthe rod. Carried by the finder rod, is a laterally extending pin 114 and e. tending through guides 115 and 1.16 is a slid ablev lift bar 117 which is connected to the hammer 44 by a link 118. This lift bar (see Figs. 13, 14 and 15) passes loosely through an opening 119 in the guide 115 and is yieldingly forced against one side of the The operation of these parts I F' 15.
